Hello everyone, I’m having an issue reading the current sense (CS) output from a VND7040 using an STM32G473 ADC. When driving a DC motor with PWM: • At ~50% duty cycle, I measure around 500 mV on the CS signal (after RC filter) using an oscilloscope•...
Hi ST,It has been more than a year since STEF48H28 was announced (document DB5404 dated Nov 2024).When is it going to be available for preview?I would prefer to use ST’s solution over a comparable device already available as evaluation module from a ...
I am currently working on a row-scanning LED matrix application using STP16DP05 and a NXP imxrt1064 MCU. I’m encountering some synchronization issues and would appreciate some clarity on the following: 1. OE (Output Enable) and Data Transfer Correlat...
I am using a L6470 and everything is working fine with one exception. When I do the initialization of the step mode and configuration registers, if the SW input is low, then the initialization does not work. If the SW input is high, then everything w...
Hi, I am using a STEVAL-WBC86TX Wireless Qi transmitter. I am going through a code and couldn't figure it out what is the meaning of the code(proprietary packet) received by the transmitter. Can any one help me to understand the meaning of this cod...
Good morning everyone! I have a fast question related with STPMIC1. I want to use it in a design with a STM32MP135 but I don't clearly see how to do it, specially the DDR rail, because I understand that i have to program it. But, in a 20-30 units pro...
Dear ST Community, Since the STUSB4710 is now NRND and no longer readily available, could you please advise what its recommended replacement is?I am specifically looking for a USB-C Power Delivery source controller that requires no firmware or only m...
I am developing a solution using a STWBC2-HP tx running from a 24VDC supply to drive a STWLC99 rx and need to use the STSC protocol to achieve 50~100W. This is for bespoke power transfer rather than a conventional charger. I am basing the design on t...
Hi, I'm trying to spec a fully integrated H-bridge for driving a small motor taking up to 6A nominal, with spikes up to 12A (looking at the VNHD7012AY, VNHD7070AY, and the VNH7100BAS). There are a lot of numbers for current limitation on the ST datas...
Hi, I'm designing a driver using 3x STSPIN9P12 to drive a Permanent Magnet Synchronous motor (PMSM). I have a ADC connected to the SNSO outputs to measure current and I am controlling the current in the MCU's control loop. I am not using the COUT a...
